Why whenever I post a picture of myself or something involving another guy (even if friend) on my story does my ex post about his new relationship?

Trust me on this, none of my guy friends think it’s coincidence. So why in your opinion does he do this? I’d love to hear more guys perspectives too.

Bump. I’d be grateful from any older guys with experience to help me with this too. Thanks.
